Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To enable both the removal of residual stress caused by a selective oxidation film layer and the formation of a deep well to be carried out by a method wherein an element isolation selective oxidation film layer is formed, then opposite conductive-type impurities are introduced into a semiconductor substrate, and the formation of a deep well and the anneal of the selective oxidation film layer are carried out by a high-temperature heat treatment. SOLUTION: A field SiO2 film 43 is formed through a LOCOS(Local oxidation of silicon) method, and element regions 44 and 45 are formed. Then, after a mask is removed, the element regions 44 and 45 of a peripheral circuit PC are masked with a photoresist 47, a memory cell array MA is exposed, and an N-type impurity ion beam 49 is made to irradiate the surface through an opening 48 of the mask 47. Then, a substrate is annealed at a high temperature of 1200 deg.C or so in an atmosphere of inert gas for three hours. By this setup, a deep N-type well 50 formed by injected impurities is activated. At this point, residual stress caused by the field SiO2 film 43 formed through a LOCOS method is relaxed.

Abstract: PURPOSE:To execute a stable mounting operation under the same pressure without being affected even by a change in a distance from a suction nozzle to a substrate by a method wherein the distance between the suction nozzle and the substrate is measured and an optimum lowering stroke of the suction nozzle is computed. CONSTITUTION:When a distance from a substrate 5 to a suction nozzle at an upper limit is designated as L and a thickness of an electronic component 1 is designated as (a), L-a is a distance up to the substrate 5 to which the suction nozzle 2 is lowered; in addition, the suction nozzle 2 is lowered by (x) in order to exert a definite proper pressure. That is to say, L-a+x is an optimum lowering stroke value from an upper-limit position of the suction nozzle. In this manner, a distance-measuring sensor 15 is introduced and the distance L from a tip position of the nozzle 2 to the substrate 5 is measured; after that, the optimum lowering stroke value is computed by using an operation part 14.

Filed: 1992-09-18
Abstract: PURPOSE:To reduce the current consumption and prolong the life of a light emitting element by detecting the ambient light in the detection region, comparing the ambient light level or its fluctuation width with the preset value, and controlling the light projection quantity of the light emitting element. CONSTITUTION:The ambient light level is detected, and whether this level is within the preset range or not is judged in the control program that light is emitted from a light emitting element and the light reflected on an object is received to detect the object. When this level is higher (lower) than the preset range, the light projection quantity of the light emitting element is increased (decreased). When this level is kept within the preset range, the light projection quantity is left as it is, then the fluctuation width of the level is judged. When the fluctuation width is larger (smaller) than the preset range, the light projection quantity is increased (decreased). When the fluctuation width is kept within the preset range, the light projection quantity is left as it is. When this interruption program is executed, the object can be detected with high precision, the current consumption is reduced, and the life of the light emitting element can be prolonged.
